Aiming at the research task of key component manufacturing technology for high-torque hub drive systems, experimental research on active design technology of surface integrity was conducted. Tests were performed in accordance with GB/T 14230 Standard Test Method for Bending Fatigue Strength of Gears, GB/T 14229 Standard Test Method for Contact Fatigue Strength of Gears, GB/T 7704 Standard Test Method for X-ray Stress Determination in Nondestructive Testing, and GB/T 13672 Standard Test Method for Scuffing Load Capacity of Gears, following the specified inspection procedures. Firstly, the GPS-2000 high-frequency fatigue testing machine was utilized, with experimental data processed using the group comparison method and screening method. The effects of process parameters including shot diameter, shot peening intensity and coverage rate on gear bending fatigue life were tested and collected. Secondly, a gear testing machine with a closed power flow structure was employed to compare the fatigue limit and fatigue life data between polished gears and unpolished gears. Thirdly, for the material 18CrNiMo7-6, with laser energy, spot diameter, number of impacts, overlap rate and protective coating as variables, the influence data of laser shock strengthening on roughness, hardness and residual stress were detected and collected. Fourthly, a series of experimental tests were carried out on 18CrNiMo7-6 carburized and quenched transmission gears combined with ISO-VG 220 lubricating oil. The tests were conducted on a gear test bench with a center distance of 160 mm, and the experimental data on the effects of transmitted torque and gear rotational speed changes on contact temperature and tooth surface damage were collected. The total data volume is 81 KB.
